dB/dt in Transient Maxwell 2D?

  Is it possible to calculate the time derivative of the flux density in a transient simulation? E.g. if I simulate a motor in 2D, can I evaluate the derivative of Bx and By over time in the complete crosssection (not only a field report).

  Hi Be, it is possible to get time derivative of flux density using Field calculator for each single time step and save it as a Named Expressions for Field Overlays visualization. To get the dB/dt for all the time steps, you can use a recorded script to automate it.

  Hi! Thanks for the answer.
  Could you maybe tell me how that is done? And also, how do I then record it as a script with the change of the current timestep?
